Title: Optimizing subsets of channels for wireless scheduling and precoding
Inventor: DAO NGOC-DUNG
IPC: H04L5/00
Filed: 2009-03-31
Abstract: In a wireless communication system in which Tomlinson-Harashima-precoded data streams are assigned to a sub-band (ie. Resource Block, RB - see fig. 1) of Orthogonal Frequency Division Multiplexed (OFDM) subcarriers, users (stations) are scheduled by optimising a matrixA-1which identifies users having the minimum mean square error (MMSE) based on their channel matrixHand allows them to be precoded last, while high MSE users requiring more protection are precoded first, in a way which accounts for different channel and noise powers amongst users.A-1is updated after each step in which a new user is added or an existing user removed from the subset according to rules J1and J2. Multiple runs of the process can be performed in order to calculate whether further optimization is possible, and schedules involving two or more sub-bands separated in time (fig. 1b) or frequency (fig. 1c) can be optimised.

Title: A control system for direct current electric motors
Inventor: GURWICZ DAVID
IPC: B60L15/20
Filed: 1969-02-25
Abstract: 1,244,259. Control of two D.C. motors. CONVEYANCER FORK TRUCKS Ltd., and SEVCON ENG. Ltd. 19 Feb., 1970 [25 Feb., 1969], No. 10019/69. Heading H2J. In a traction system having series connected motors A, B, the motor A will tend to accelerate leading to a stalled condition of motor B if the wheel driven by the motor A leaves the ground. As the speed of the motor A increases in relation to that of the motor B, the output of a speeddifferential sensing device causes closure of contacts 2a of relay 2 whereby contactor Y is changed over. The motor A is by-passed through conductor 11, the effective voltage applied to motor B being reduced by decreasing the pulse rate of semi-conductors in the motor circuit. The contacts 2a re-open when the speeddifferential is reduced, undue frequency of operation of the contacts being prevented by providing the sensor with a wide differential or by using a timing device. When the wheel driven by the motor B leaves the ground, contacts 1a of relay 1 close to energize contactor X. The speed sensor may comprise tachometer generators attached to each armature, or, a relay responsive to the armature voltages. An overide device allows a speed differential when the vehicle is being turned so that the drive to the outer wheel is not removed. Alternatively, the motor driving the inner wheel during turning may be open or short-circuited, or reversed. The back EMF of a run-away motor may be reduced by short-circuiting its armature. The contactors may be replaced by static switches.

Abstract: The invention comprises a thiophosphoric acid ester of the general formula:  <FORM:0843309/IV(b)/1> wherein R is C1-C4 alkyl, Y is an oxygen or sulphur atom and X is a sulphide, sulphoxide or sulphone group.  The compounds in which X is a sulphide group may be obtained by reacting a -chloro (or bromo) methyl, cyclohexyl thioether with an appropriate O,O-dialkylthiol-(or thionothiol-) phosphoric acid in the presence of an acid binding agent or with a salt, e.g. ammonium salt, of such O,O-dialkylthiol (or thionothiol-) phosphoric acid. Compounds in which X is a sulphoxide or sulphone group may be obtained by first preparing the sulphide compounds as above and then oxidising them either with hydrogen peroxide, preferably at a temperature of up to 50 DEG C. to form a sulphoxide, or at 50 to 100 DEG C. to form a sulphone, or with potassium permanganate preferably at a temperature of up to about 10 DEG C. to form a sulphone. Examples are given for the production of compounds in which X and Y in the formula are both sulphur and each R is ethyl, methyl, and isopropyl respectively and the corresponding sulphoxide compounds (i.e. in which X is -S(O)-) and of compounds in which X is a sulphide group, Y is oxygen and each R is CH3 and C2H5 respectively and the corresponding sulphones (i.e. in which X is -SO2-).  The products have insecticidal properties (see Group VI).ALSO:An insecticidal composition comprises one or more thiophosphoric acid esters of the general formula <FORM:0843309/VI/1> wherein R is an alkyl radical containing up to 4 carbon atoms, Y is an oxygen or sulphur atom and X is a sulphide, sulphoxide or sulphone group (see Group IV(b)) and a solid or liquid carrier or diluent.  Specified carriers are talc, chalk, bentonite, clay, water (if necessary with an emulsifier), alcohols, ketones and liquid hydrocarbons.  Known insecticides and/or fertilizers may also be present.  A typical composition is obtained by mixing a compound of the above formula in which X and Y are each sulphur and R is C2H5 with acetone, adding benzyl hydroxy diphenyl polyglycol ether as emulsifier and then diluting with water.

Title: System of control and stabilization of the frequency of electronically tuned oscillator tubes
IPC: H03B5/18
Filed: 1955-04-06
Abstract: 795,059. Automatic frequency control systems. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. April 6, 1955 [April 6, 1954], No. 10129/55. Class 38 (4). An oscillator 14 is swept over a frequency range, on operating potential being switched on, by the voltage developing across a charging circuit 19, 20 forming, with a valve 18, part of a potential dividing circuit connected to an electrode 24 of the oscillator, whose potential varies the frequency of the oscillator, until the frequency band of a discriminator 11 is reached whereupon an amplified output of the discriminator is applied to the control grid of the valve 18 to vary its resistance and stabilize the frequency at a value near to, but slightly different from, that of the discriminator. Also a gaseous tube 20 forms part of the potential divider so that, if the discriminator frequency band is passed over without stabilizing control becoming effective the tube 20 fires to discharge the capacitor 20 and the frequency sweep is resumed. The discriminator may be a tunable cavity resonator slightly off-tuned from the desired oscillator frequency so that its output increases as the desired frequency is reached. Its output may also be amplified by a D.C. amplifier 17 having a threshold bias so that the effective bandwidth of the resonator is reduced and greater accuracy obtained. The oscillator tube may be a reflex klystron, or a backward travelling wave valve of types with or without a transverse magnetic field. Specification 699,893, [Group XL (a)], is referred to.
